Chlorophylls and carotenoids
WebNotes and trouble shooting tips. “Normal” pigment values. In a typical non-stressed mesophyte leaf, chlorophyll a+b concentrations should be in the range 200-700 µmol m -2. Carotenoid to chlorophyll ratios should be 30-60 for neoxanthin, 100-220 for lutein, 40-80 for VAZ cycle pigments, 50-100 for α-+β-carotene. WebBoth chlorophyll a and carotenoids are pigments, but they absorb light at different wavelengths. Because it emits electrons, chlorophyll a is highly significant. Carotenoids are accessory pigments that support chlorophyll in their role as light-absorbing substance during photosynthesis. Why do plants produce pigments other than chlorophyll?
